Application filed. July 7, 1919., Serial No. 309,083.

To (,(ZZ wfzom it may concern:

Be it known that 1, Jules M. lVAnnLOW, a citizen of the United States, residing at Ada, in the county of Pontotoc, and State of whereby anyone of a number oil difi erent type blades can 1 e easily and quickly associated with or detached from the handle when desired.

The nature and advantages of the inven-.

tion will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

Tn the drawing forming part of this specilication like numerals of reference indicate similar parts in the several views wherein Figure l is a view of a hoe constructed in accordance with my invention.

Figure 2 is a vertical sectional view taken on the line through the blade and the connecting means therefor.

Figure 3 is a detail sectional view taken on line 33 of Figure 2.

Figure 4: is a fragmentary front view.

Figure 5 is a fragmentary sectional view.

Figure 6 shows several types of blades designed for use in connection with the invention.

Referring to the drawing in detail, 10 indicates hoe blade of well known construction, 11 a handle therefor, and 12 the socket connection between the handle and blade, respectively. Upon reference to Figure 3 1t will be noted that this socket connection is formed to provide an elongated substantially flat end portion l3 adapted to be at. urged against one side of the blade '10. The lower ed of this flat end portion is provided with a notch 14; which is adapted to receive the offset extremity l5 of an adjusting screw 17 which is adjustable transversely through the socket member at a point immediately at the rear of the flat end portion 13. The upper end of the screw is provided with a winged nut 18, while the offset extremity of this screw is provided with a head 19. The opposite end or edge of the frame portion 13 is bent forwardly and downwardly to pro also connected to vide a flange 20 which is of short pins 21.

the portion 13 by means The blade 10 at point in its surface is provided with a key hole slot 22 which receives the offset headed extremity of the adjusting bolt, while the upper edge of the blade is provided with notches 24 which receive the pins 21 when this edge of the blade is positioned between the flat portion 13 and. the flange 20 thereof. If desired, a. small plate 25 may be secured to one side of the blade to reinforce the latter at its point of connection with the pins 21, in which instance the plate 25 is also provided with notches -26 which coincide or aline with the notches 24 of the blade. parts, the thumb nut is turned in the proper direction to permit the headed extremity of the adjusting screw to assume a position below the adjacentedge of the flat portion 13 of the socket. The head of the adjusting screw is then inserted through the enlargedportion of the key hole slot of the blade, during which time the upper edge of the blade is positioned within a recess formed by the flange 20 with the notches thereof arranged to receive the pins 21. Manifestly, as the thumb nut is tightened, the offset extremity of the adjusting screw is lifted into the small or reduced portion of the key hole slot, moving the blade slightly so that the notches thereof will receive the pins 21. The pins manifestly prevent turning of the blade relative to the socket connection. The parts can be just as easily disassembled by loosening the thumb nut sufficient to permit the headed extremity of the adjusting screw to be removed from the key hole slot of the blade.

In Figure 6 l have shown a number of different type blades, certain. of which are provided with tines and all of which except the rake have duplex working extremities. Aside from this fact, the blades A. and B in Figure 6 are constructed and attachr-wfl to the handle inv the same manner as described in connection with the blade 10. In each of these instances, the blade is provided with a key hole slot 30 and spaced notches 31 at one edge of the body portion thereof. They are also provided with reinforcing plates 82 having notches alined with the notches 31.

The rake indicated at C in Figure 6 is provided with a key hole opening or slot between its intermediate tines 36, while the upper edge of the rake is also provided To associate the l with the spaced notches 37 and a reinforcing plate 38 having the notches 39 alined with the notches'37. The rake is associated with the handle in the same manner as that 5 disclosed and described in connection with the blade 10. The blade indicated at D in Figure 6 varies from the other blades in that it is provided with a transverse slot L0 at an appropriate point in its length and that one edge of the slot is formed with the spaced notches for the reception of the pins 21. lhe reinforcing plate 42 is secured to one side of the blade as the notches 43 in alignment with the notches 41. The blade is otherwise constructed the same as the other blades so far as the invention is concerned, havinga key hole slot el-t for the reception of the offset extremity of the adjusting bolt 17 and adapted to be secured to the handle in the same manner as the blade 10.

While I have shown and described what I consider the preferred embodiment of the invention I desire to have it understood that I donot limit myself in this connection, inasmuch as such changes may be resorted to when desired as fall within the S00 e of what is claimed.

aving thus described my] invention what I claim is Y A tool of the class described comprising,

a blade, a handle provided therefor having a socket connection with the handle and blade, the socket connection being formed to provide an elongated substantially fiat end portion adapted to be arranged against one side of the blade, an adjusting screw adjustable transversely through the socket I of the latter, the opposite end of the flat portion being bent forwardly and backwardly to provide a flange which is connected to the flat end portion, the blade having a key hole slot "formed therein to receive the offset headed extremity of the adjusting screw, and the upper edge of said blade having notches formed therein to receive pins for connecting said flange to'the end portion, a reinforcing plate se cured to one side of said blade and having notches therein which coincide'with the notches of the blade.

In testimony whereof I a'lfix my signature.

JAMES MORGAN WARDLOW.
